Description
FIELD
The present embodiments pertain to a disposable dual surgical
stapler gun and more specifically, a dual surgical stapler gun and
a method for the use of a dual surgical stapler gun as a tissue
fixation device.
BACKGROUND
In normal surgery, simple sutures using thread have often been
used.
A simple suture involves using a plurality of simple stitches each
with a knot to hold the skin together. There are situations when
these simple sutures are unsatisfactory because the skin overlaps
during healing causing scarring. Surgical situations exist wherein
sutures with a needle and thread simply take too long. For example,
situations when the patient should not be kept under anesthesia any
longer than necessary would require a quick method of closure.
Extended time under anesthesia increases the patient's risk of
complications.
To provide a fast method to hold skin together, staples were
developed having one of three basic shapes, a C-shape, a U-shape
and a circular shaped member. These simple staples have advantages
over the simple sutures for quickness in implementation, but has a
negative effect in that the skin usually overlaps during healing.
Overlapping skin can cause scarring or a ridge to form. This ridge
or scar can delay the healing process as well as be a cosmetically
undesirable feature. Also with overlapping skin, the healing
process is prolonged.
As an alternative to simple suturing, mattress suturing was
developed. The mattress suture prevents overlapping of the edges of
the incision and improved the healing process by quickening the
healing process of the skin and reducing the incidence of unsightly
scarring of the skin.
The mattress suture, regrettably takes an even longer time to
implement than the simple suture. The mattress suture causes the
wound to heal faster and reduces scarring but requires more
anesthesia time for the patient, which is can have negative
effects. This mattress type of suturing involves placing on each
edge of the incision, a stitch immediately near the edge of an
incision or wound and then making a second stitch further from the
edge of the incision or wound to approximate the two edges of the
incision or wound and reduce tension on the wound while preventing
an overlap of the edges of the incision.
The present embodiments were designed to provide the advantages of
the mattress suturing technique with the improved quality of a dual
staple system.
The predominant form of staple includes a central portion, either
straight or slightly curved, with bilateral opposing side portions
that are sharply beveled so as to penetrate the skin easily. This
form of staple is generally applied utilizing a stapling apparatus
that forcefully drives the opposing beveled side portions through
the tissue margins in a ninety degree arc so that these beveled
opposing side portions are generally facing one another at the
completion of the stapling operation. The bending of the opposing
beveled side portions form generally parallel planes into a
generally horizontal plane is often accomplished utilizing a ram
and opposing ram plate that cooperatively forcefully bend the
opposing beveled side portions during a stapling operation.
Another conventional surgical staple includes a generally U-shaped
fastening member having legs that are received in two bores of a
receiver member. This type of surgical staple is limited by the
need to grasp the members both above and below the tissue
plane.
A third surgical staple involves an open circular-shaped member,
which when closed, has the free ends laterally disposed with
respect to each other forming a split-ring configuration.
A need exists to prevent the overlap of the skin when drawing the
edges of the skin together. A need exists for a disposable dual
surgical stapler gun that is fast to use and will help keep the
edges of the skin together for an extended time without an overlap.
A need exists during the healing period after surgery for a secure
stapling system that holds the skin together without an overlap to
insure better healing and less scarring of the skin.
The present embodiments have been developed to meet these
needs.
SUMMARY
The present embodiments relate to a dual staple disposable surgical
stapler gun, wherein the gun fires two staples simultaneously to
close an incision in the skin without the skin overlapping. The
stapler simultaneously fires two staples in a staggered formation
to give a closer and stronger approximation of the edges of the
incision.
The dual staple disposable surgical stapler gun consists of a frame
structure adapted to be held by a hand with a grip having a handle.
The first staple track is disposed on top of the second staple
track in a staggered relationship, each staple track being adapted
for holding staples. The first staple track and the second staple
track each have an advancing blade and a spring mechanism.
A translatable driver manually actuates both staple tracks to eject
a single pair of staples simultaneously by the hand. The pair of
staggered staples eject simultaneously for engagement on both sides
of the incision forming a mattress suture. The first staple engages
a first arm close to a first edge of the incision and a second arm
a distance from the second edge of the incision and the second
staple engages a first arm close to a second edge of the wound and
the second arm engages a distance from the first edge of the wound
to achieve dual staple mattress suturing.
There includes a biasing means for returning the translatable
driver from a staple ejecting position to a staple reloading
position. The translatable driver having a force transmission
member linking together the translatable driver and a connecting
end portion engageable with a spring connected to the translatable
trigger portion.

listed Figures.
DETAILED DESCRIPTION OF THE EMBODIMENTS
Before explaining the present embodiments in detail, it is to be
understood that the embodiments are not limited to the particular
embodiments herein and can be practiced or carried out in various
ways.
Embodied devices herein are for a disposable dual surgical stapler
gun that simultaneously propels two surgical staples in a staggered
fashion for closing incisions in skin. In general, the surgical
staples have a body portion constructed from a rod and have a
planar structure. The body portion consists of a crown with leg
projections from each end. Each leg comprises a skin piercing
projection to assist in the staple being inserted into the
skin.
In a pre-stressed situation, the widths for a surgical staple to be
used with humans are typically between 2.5 mm and 3.5 mm and the
second widths are typically between 1.5 mm and 2.5 mm. For humans,
the most preferred width contemplated is, for the first width, 3 mm
and for the second width is 2 mm.
If the surgical staple is designed for use with large animals, such
as a horse or cow, giraffe or other large zoo animal, the first
width is typically 7.5 mm to 10.5 mm and the second width is
typically between 3 mm and 7.5 mm. The preferred width for large
animals is typically 9 mm for the first width and 6 mm for the
second width.
The skin piercing projections are adapted to accept stress, such as
from a surgical stapler. An example of a surgical stapler is the
Ethicon Proximate RH 35W that is used to implant the surgical
staple in the skin of a human or an animal. The surgical stapler is
used to embed the staple operated manually and transform the
generally planar structure of the body of the surgical staple to a
stressed position.
In the stressed position, where the piercing projections are
disposed on skin on opposite sides of a wound. The piercing
projections are then bent by the staple into essentially the same
plane holding the skin together in a position tantamount to that of
a mattress suture.
Upon cessation of the application of stress, the surgical staple
maintains the stressed position enabling the surgical staple to
draw opposite margins of skin toward each other in a
non-overlapping manner. When the skin piercing projections are
bent, the two projections or arms are in an angular relation to
each other at 180 degrees, but variations from this angle would
still work, if the variation is no more than 20 degrees.
In an embodiment, the surgical staple is made from a rod of a
lightweight, non-rusting alloy, such as stainless steel.
In another embodiment, the surgical staple is adaptable for human
use and small non-human animals. A small non-human animal that this
staple would work on could be a dog, a cat, a raccoon, a chicken,
or similar creatures. For such "small animal" use, the pre-stressed
staple preferably has a height between 4 mm and 6 mm, a length
between 2 cm and 3 cm, and a diameter of the rod from between 0.5
mm to 0.8 mm.
Alternatively, the novel surgical staple can be for large non-human
animals, like giraffes, elephants, other zoo animals, horses, cows,
large birds, dolphins, or similar large animals with a skin or skin
like covering. In this larger embodiment, the surgical staple
comprises a height between 12 mm to 18 mm, a length between 6 cm
and 9 cm, and a diameter of the rod between 1.5 mm and 2.4 mm.
The body of the staple is can be a solid rod structure, but the
body can be a hollow bendable rod as well.
With reference to the figures, FIG. 1 depicts an embodiment of a
dual staple system embedded in skin closing an incision (100). The
dual surgical staple system includes two staples, a first staple
(60) and a second staple (70), per staple location. Each staple (60
and 70) includes a crown (61) with two ends. Each staple includes a
first arm (62) and a second arm (64) attached at each end of the
crown (61). The arms extend from the crown in a direction
substantially perpendicular to the crown when the staple is in an
unstressed position.
As a method, the two staples are loaded into a surgical stapler.
The surgical stapler is located over an incision in the skin that
needs to be closed. The stapler is activated and the arms of each
stapler are inserted into the skin.
As depicted in FIG. 2, the first arm (62) is inserted in the skin
(50) near the incision (100) and is bent towards the incision
(100). Typically, the first arm (62) intersects the incision in
order to ensure that the two sides of the skin are held together.
In one embodiment, the first arm (62) is bent so that the bended
end is close to the surface of the skin, as depicted in FIG. 2. The
dual staples, when bent into the skin around the incision,
generally can form a rectangular shape or an inverted G-shape with
a gap.
The second arm (64) is inserted in the skin (50) away from the
incision (100) and is bent towards the incision (100) in order to
secure stabilization of the union of the two edges of skin.
The disposable dual surgical staple gun causes no skin overlap,
promotes faster healing of the skin, and it is faster to close the
skin incision with staples which reduces the need for anesthesia
time for the patient, which can be a lifesaving step. Often
prolonged exposure to anesthesia cannot be tolerated by sick
patients.
In another embodiment, each arm has skin piercing projections in
order to insert into the skin easier. The skin piercing projections
can be either a pointer projection, a chiseled projection, a skewed
projection, or combinations of these projections.
In an embodiment of the invention, the staple of the disposable
dual surgical staple gun uses skin piercing projections with
pointed ends that resemble a chisel-like structure. Medical needles
use a "beveled" or chisel-like structure to provide a means to
invade the skin with maximum ease and minimal pain. In another
embodiment, each of the skin piercing projections can have a
beveled end.
In another embodiment of the surgical staple, the pre-stressed
surgical staple is placed upon the skin, and then the staple is
stressed, drawing the skin piercing projections slightly together,
with the first and second skin piercing projections becoming
disposed in a generally horizontal plane relative to the body of
the staple.
The mattress staple can be used with all surgical skin incisions.
Another embodiment is a method of use for applying a mattress
staple that is usable in adults, children, or even non-human
animals, such as thoroughbred horses.
The present embodiment relates to a dual staple disposable surgical
gun, wherein the gun fires two staples in a staggered formation
simultaneous to close an incision in the skin without the skin
overlapping. The dual staple disposable surgical gun has a frame
structure, adapted to be held by a hand with a grip having a
handle.
The dual staple disposable surgical gun has a first staple track
and a second staple track each with an advancing blade and a spring
mechanism. The first staple track is disposed on top of the second
staple track in a staggered relationship, each staple track being
adapted for holding staples. A translatable driver is positioned on
the dual staple disposable surgical gun for manually actuating both
staple tracks to eject a single pair of staples simultaneously by
the hand. The pair of staggered staples eject simultaneously for
engagement on either side of the incision forming a mattress suture
and wherein the first staple engages a first arm close to a first
edge of the incision and a second arm a distance from a second edge
of the incision and the second staple engages a first arm close to
a second edge of the wound and the second arm engages a distance
from the first edge of the incision to achieve dual staple mattress
suturing. The dual staple disposable surgical gun additionally
includes a biasing means for returning the translatable driver from
a staple ejecting position to a staple reloading position. The
translatable driver having a force transmission member linking
together the translatable driver and a connecting end portion
engageable with a spring connected to the translatable trigger
portion.
In an alternate embodiment the dual staple disposable surgical gun
can consist of a frame structure comprising a first staple track
portion inserted into a second holder portion.
In another embodiment of the dual staple disposable surgical gun
the first and second staple tracks each comprise a back and a top
and the first and second staple tracks are connected back to
back.
In yet another embodiment the dual staple disposable surgical gun
fires at least two staples simultaneously each time it is fired.
After firing the two staples are staggered in a position from each
other across the incision.
In yet another embodiment dual staple disposable surgical gun
comprises the gun using staples that have a skin piercing
projection comprising of a point projection, a chiseled projection,
or a skewed projection. The staple can also comprise a lightweight,
non-rusting alloy of a metal. Each staple can have:
a. a height ranging from 4 mm to 6 mm;
b. a length ranging from 2 cm to 3 cm; and
c. a diameter of the rod ranging from 0.5 mm to 0.8 mm.
In another embodiment dual staple disposable surgical gun can
comprise a gun formed from a crystalline polymer, or a metal.
Wherein the gun first width ranges from 2.5 mm to 3.5 mm and the
second width ranges from 1.5 mm to 2.5 mm.
The present embodiment also comprises a method for surgically
stapling an incision using the simultaneous injection of offset
twin surgical staples. The steps begin by inserting surgical
staples into a dual staple disposable surgical gun. The surgical
staples each comprise a crown comprising two ends, a first arm, and
a second arm attached at each end of the crown. The arms of the
staple comprise a skin piercing projection, wherein the arms extend
from the crown in a direction substantially perpendicular to the
crown when the staple is in its initial shape. The dual staple
disposable surgical gun comprises a gun that fires two staples
simultaneous to close an incision in the skin without the skin
overlapping.
The next step for surgically stapling the incision comprises
placing the dual staple disposable surgical gun over the incision
and activating the stapler by squeezing the grip to simultaneously
insert a first staple from a first track and a second staple from a
second track into the skin. By activating the stapler the first arm
of each staple engages the skin nearest the incision on opposite
sides of the incision. The crowns of each staple locate adjacent
and parallel to one another, and the second arms of each staple to
engage the skin away from the incision on opposite sides of the
incision The dual staple disposable surgical gun then bends each
arm on the staples forming an inverted G-shape with a gap.
In another embodiment the step of using the dual staple disposable
surgical gun bends each arm to ensure that the first arms
intersects the incision.
In yet another embodiment the step of using the dual staple
disposable surgical gun bends each arm thereby closing the incision
in the skin without the skin overlapping.
